Enum rustc_session::config::SplitDwarfKind

pub enum SplitDwarfKind {
    Single,
    Split,
}

Split debug-information is enabled by -C split-debuginfo, this enum is only used if split debug-information is enabled (in either Packed or Unpacked modes), and the platform uses DWARF for debug-information.

Some debug-information requires link-time relocation and some does not. LLVM can partition the debuginfo into sections depending on whether or not it requires link-time relocation. Split DWARF provides a mechanism which allows the linker to skip the sections which don’t require link-time relocation - either by putting those sections in DWARF object files, or by keeping them in the object file in such a way that the linker will skip them.

Variants

Single

Sections which do not require relocation are written into object file but ignored by the linker.

Split

Sections which do not require relocation are written into a DWARF object (.dwo) file which is ignored by the linker.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
